Monterey Breakwater 



Monterey Harbor, California 



Date(s) Construction and Rehabilitation History 



1932 The construction of a 1 ,300-ft-long rubble-mound breakwater was 

 completed (Figure 20). The crest el of the structure was +10 ft 

 mllw, and the side slopes were 1V:1H on the harbor side and 1V:1.5H 

 on the ocean side. The armor stones used weighed 10 tons each. 



1934 A 400-ft rubble-mound extension to the breakwater was built under 



the Public Works Administration Program (Figure 20). The extension 

 was constructed with a crest el of +10 ft and with IV: 1H side 

 slopes on the harbor side. Side slopes on the ocean side were 

 1V:1.25H from the existing ground to el -16 ft mllw and 1V:1.5H 

 from el -16 to +10 ft mllw. Armor stones used ranged from 4 to 

 12 tons. Total cost of the breakwater through 1934 was $652,951. 



1960 Improvements consisting of a S.SOO-ft-long north breakwater and a 

 1 , 100-ft-long east breakwater (Figure 20) were authorized. These 

 structures were never constructed; however, model tests were 

 conducted to optimize the improvements (Chatham 1968). 



1969 Model tests for a proposed tribar breakwater section were conducted 

 (Davidson 1969). 



1974 The project authorized in 1 960 was reclassified as inactive due to 

 lack of local support. 



1986 There is no history of maintenance of the breakwater, and it is in 

 satisfactory condition.
